California Drop Riffle Sluice with Siphon Flare Shopify Collective Mats may need minor finalThe California Drop Riffle Sluice with Siphon Flare is back by popular demand and better than before! Weighs less than 2 pounds. The leading edge (siphon flare) has an angled lip that blocks the water going under the sluice and forces it to the top. In a river, water on the underside moves faster than surface water. Very easy to set in place because the diverted water flow forces the water to the top, forcing the sluice to almost stick to the rocks.
